Signal
GtkComboBox::format-entry-text
Description [src]
Emitted to allow changing how the text in a combo box’s entry is displayed.
Connect a signal handler which returns an allocated string representing
path. That string will then be used to set the text in the combo box’s
entry. The default signal handler uses the text from the
GtkComboBox:entry-text-column model column.
Here’s an example signal handler which fetches data from the model and displays it in the entry.
static char *
format_entry_text_callback (GtkComboBox *combo,
const char *path,
gpointer user_data)
{
GtkTreeIter iter;
GtkTreeModel model;
double value;
model = gtk_combo_box_get_model (combo);
gtk_tree_model_get_iter_from_string (model, &iter, path);
gtk_tree_model_get (model, &iter,
THE_DOUBLE_VALUE_COLUMN, &value,
-1);
return g_strdup_printf ("%g", value);
}
